Y application inea July 26,1920. serieu No. 398,991.

Be itknown that I, HENRY Minneapolis, in the county of Hennepin and State of Minnesota, have invented a 'new and useful Churn and 'Biitter-lVorker, of which the following is a specification. f v

This invention relates to. Vchui-ns f of "the 'power operated type, and more particularly to a novel form of churn includingbutter.- working means..

The primary object of the inven'tionis to provide a churn of this characterhaving suitable clutch mechanism wherebythe buti ter working rolls may be` moved into andV out of operation at the will.v of the attendant?" thuseliminating the necessity of stopping the churn to a'ccomplish'rthevworking of the? butter.

A' further provide means for automatically:relieving the gaswithin the churn,themeans'being"h timedV to cause Y thek operation of" a Valvefat predetermined intervals. V1' f l With the foregoing and other objects view-which will `appear as Ythe* description proceeds, theA Invention yresides-In' the com-,1i

Withinthe scope of what is claimed,xwit`hout departing` from the spiritV of the invention.l Referring to the drawings 4Figure 1l illustrates a longitudinal-l seo'-V tionalview through a churnconstructed in accordance with the' present invention.

Fig. 2 illustrates an end Velevational viewV ofthe same, and i Fig. 3 illustra-tesl a ytransverse sectional,

Referring to the drawings in detail, the.`

reference-character fdesignates` the supporting legs ofthechurnr, which have right angled extremities 6 bygmreans'of which the l churnV VVis' supported in yan upright' position,

the upper extremitiesoffthersupporting :leg being provided with heads indicatedfat'r?, which the churnj is s uppor.tedf.

' The' churn includes thedrumforbody portion 8 which is provided with a partition 9 dividing the churnV into a churning? :corn-V partment and a gear casing 11,-'. the partition havingl connection with .the-walls .ofgthechurn to prevent foreignmatter contained VJ.'

that movementof thexgear 28"*in1'fone {direction will cause the clutch pin 33 to move into the cut out portion 36 of the pinion 35 to clutch 'the pinion 35 to the elongated gear 28, which movement is accomplished through the medium of the clutch operating rod 24,

which as before stated has indirect connection with the gear wheel 28. Y

Formed integral with the gear 31, is a pinion 37, which pinion 37 also meshes with the pinion 35, and this pinion 37Y also forms a part of the disk 38, to which attached the laterally extending arms 39, that carry the friction disks 40 and 41 for purposes 'to be hereinafter more fully described.

As shown, the friction disk 42 is formed integral with the shaft 15, and is provided with suitable fraceways to receive the ball bearings 43, which ball bearings also operate against the movable disk 44 which operates on the hub 45 of the arm 46, the lower endV of lwhicharm has connection with the shaft 29.

Friction disks 447 are e provided with i tongues .48.adapted to be positioned in grooves 49 formed in the hub 45 to prevent rotation of these disks, for braking purposes. The disks 50 which are carried by- A the shaft 15 are also provided with suitable grooves in shaft 15. From the'foregoing it is obvious that when lever 68 1s released to thev right, thespring 21 shoves pulley 17 out and with it'shaft 15 and disk 42,

compressing the group of disks 41 between Y fseparate Yand loseV their vdriving power.

disks 42 and 38 so that the friction generated causes the operation ofV the churn. When' lever 68 is moved to the left compressing spring 21 the group of disks 41 lever 68 is' moved farther, the group of disks 40 are compressed` between disk 46` Y and disk 44 by action of the ball bearing 43 and disk 42 causing the churnrand all fits working parts toY remain stationary while disk 42, shaft 15 and pulley 17 are still' free to revolve. Y

Rotary movement of the arm 26 is prevented by means ofl the pins 51, which eX- tend laterally from arm 46, and contact with the arm 26, however the arm 26 may be moved-into engagement with Ythe pins 52, carried by the pinion 53, for preventing rotation of the pinion 53.

This pinion 53 imparts rotary motion to the pinion 54 which is carried by theV shaft 55 mounted on the partitioning wall Q, the pinion54 however being designed to impart rotary' movement to the pinion 56 i mounted on one extremity of the shaft 57,

the opposite extremity of the shaft supporting the sprocket wheel 57, which transmits motion to the sprocket wheel 58 through the medium of the chain 59.

.Thus it will bessen that rotary movement is imparted to the pinion 60, which in turn imparts rotary motion to the pinion 61,

vat predetermined intervals to which pinions 60 and 61 have connection with the shafts 62 that support the butter working rolls 63, so that when the clutch actuating rod 24 is moved to a predetermined position, the butter working rolls are rotated. v .Y The pinion 64 is Secured to the partitions* ing member 9 by means of the flange 65, the teeth 66 of the pinion 64 being in mesh with the teeth 67 of the elongated gear 28, f so that movement of the kgear 28 will cause a relative movement of the pinion 64 with the result Vthat the churn or body portion be rotated. arried by the bracket member 30, 1s an arm indicated at l68 which extends at right angles and is provided with a shoe 69 adapted to contact with the movable pin 70 which kpressed valve member 73.Y F rom the foregoing it is obvious that upon rotation of the arm 68, the valve member 73 is rotated I releasev gases from the compartment 10.

In operation when lever 25 is moved to the' right it carries with it lever 26, and lever 26 shoves pinion along shaft 29 so that the jaws 33 on pinion 28 are brought intoengagement with the j aws 34. on gear 32 causing the churn Ato revolve at the churning (or high) speed,when lever 68 is released to allow the clutch disks in 41 to become engaged. When lever 25 is moved to the left (or in) gear-28 is moved out, so that jaws 33 are brought into engagement with jaws 36 -on gear Y 35. As lever 26 moves pinion 28 into connection with the lowspeed v( or butter working) gear 35, it also engages pins 52`0n gear 53 causing V gear 53 to be held in a stationary position so ating rod 24 is moved'forwardly to lcause the arm 26 to contact with the pins 52 to c prevent rotation of the pinion53. vIt, is therefore obvious that as the churn continues to revolve around the pinion 53, rotary movement is imparted'to the butter working rolls 63 through the pinion 56, sprocket wheel 58,'and pinions 60 and 61;

When the churning operation is completed it is only necessary to movev lever 24 in or toward the churnto throw the churn out ofthe high or churning speed into the low or butter working speed, and to bring the butter working rolls into action. l

To facilitate 'the cleaning of the churn it is only necessary to remove plugs 70and 71 and yshaft 72 to enable Vthe butter working rolls 63 to {be removed from the churn.,V

VThe outer surface of rolls 63 are provided' With spiral 'corrugations Which enables the movement of the rolls Within the churn to be lateral, and more perfectly controlled.

I claiml l. In a churn, supporting legs, a drum supported by the supporting legs, a partition disposed Within the drum for partitioning the drum into a gear casing, an arm having connection With the partition, a gear having internal teeth formed integral with the arm, means including friction disks for causing the operation of the gear and drum, butter Working rolls supported Within the churning compartment, a pinion having connection With each of the butter Working rolls, a pinion supported centrally of the partition and causing the operationof the pinions of the butter Working rolls, and means for holding the pinion supported centrally of the partition member stationary, to cause the operation of the butter Working rolls.

2. In a churn, supporting legs, a revolving drum mounted on the legs, a partition Within the drum and dividing the drum into a gearing compartment and a butter Working compartment, a gear having a flange for securing the gear to the partition, an operating shaft, a bracketmember movable onV the shaft and carrying an elongated gear,

partitioning the VYdrum into a gearing compartment, and a butter Working compartment, gearing Within the gearing comparty ment for rotating the drum, buttervvorking rolls Within the butter Workingv compartment, gearingA for operating the butterV Working rolls,means for throwing the rst mentioned gear ntooperation t0 causethe rotation of the drum, said means adapted to throw the butter Working rolls intoV opera-4 tion, when they rotation of the drum has" ceased, and meansfor exhausting gas'from the butter Working compartment. In testimony that I claim the ture in the presence of two Witnesses.
